Axis couplings

11.1

Coupled motion (TRAILON, TRAILOF)

Function
When a defined leading axis is moved, the coupled motion axes (= following axes) assigned
to it traverse through the distances described by the leading axis, allowing for a coupling
factor.
Together, the leading axis and following axis represent coupled axes.
Applications
● Traversal of an axis by means of a simulated axis. The leading axis is a simulated axis
● Two-sided machining with two coupled motion groups:
Syntax
TRAILON(<following axis>,<leading axis>,<coupling factor>)
TRAILOF(<following axis>,<leading axis>,<leading axis 2>)
TRAILOF(<following axis>)

and the coupled axis a real axis. In this way, the real axis can be traversed as a function
of the coupling factor.
1st leading axis Y, coupled motion axis V
2nd leading axis Z, coupled motion axis W
